ASR-33 Teletype

  • ASR-33 Teletype

  • The Teletype Model 33 (including the ASR-33, Automatic Send-Receive) was an electromechanical teleprinter introduced by Teletype Corporation in 1963.
  • Featuring a built-in keyboard, impact printer, and paper tape punch/reader operating at 110 baud (10 characters per second), the ASR-33 became the iconic early interactive computing terminal across time-shared minicomputer networks of the 1960s and 1970s.
  • It was on an ASR-33 Teletype on a Saturday morning at age 10 that I typed in my very first computer program (a four-function calculator in HP 2000 BASIC), which ran 100% bug-free on the first attempt. See Testing If the Computer Could Do Math and My First Bug-Free Program.
